Manchester United youngster Adnan Januzaj's contract negotiations stalled following the departure of Sir Alex Ferguson as manager last summer his agent confirmed.

Sportsmail revealed in September that a stand-off had developed between the club and player although as other top clubs look to swoop on the teenager who is out of contract at the end of the season talks have reopened.

Dirk De Vriese - the representative of the 18-year-old Belgian - has said a number of leading European clubs are weighing up a move for Januzaj.

Although he refused to divulge the names of the clubs considering an offer Sportsmail understands Juventus and Manchester City have both registered an interest while Bayern Munich and Barcelona are also monitoring the situation.

With negotiations ongoing at United the Belgian is now facing a potentially career-defining decision as to where his future lies.

‘I’m not going to say which teams are interested in him but I can tell you that there is interest from several European clubs’ De Vriese is quoted as saying in an interview with Voetbal Niews.

‘The departure of Sir Alex Ferguson meant that there was a break in the negotiations. We are back working on the calls and will see how it goes.

‘Adnan’s family have given me the permission to communicate. As it is only me involved there can be no misunderstandings in the media.’

Despite the precarious nature of the situation - intensified by United’s recent history of losing talented teenagers Paul Pogba and Zeki Fryers to Juventus and Tottenham - the Old Trafford club do remain confident of agreeing a new five-year deal that would tie Januzaj to the club until 2018.

Januzaj is already one of the highest earning youngsters at Old Trafford and Sportsmail understands United are putting the finishing touches to a new deal that will recognise the emergence of Januzaj as the club’s most exciting young talent following an impressive start to the season under new boss David Moyes.

It is believed that the initial idea was to loan out Januzaj for this campaign but those plans were shelved after the player shined so brightly on the club’s pre-season tour of Australia and Asia while he has since made cameo appearances for the first-team from the substitute’s bench against both Crystal Palace and West Bromwich Albion in the Premier League.

United are anticipating a deal will be reached with regular tastes of first-team football expected to entice the player into remaining at Old Trafford.

Last week manager David Moyes said: ‘We really think an awful lot of Adnan. He is a Manchester United player. I am sure he will stay. He is keen to stay.’

There are also question marks over Januzaj’s international allegiances with the player eligible to represent four countries. He was born in Belgium to Kosovan-Albanian parents while his heritage also allows him to play for Turkey and Serbia.It is understood that Januzaj has repeatedly turned down call-ups in the lower age groups for Belgium with his family and friends keen for him to represent Albania.
